Hi all, Please help me if you have similar experience and/or know how to resolve it. Thanks very much.
Yesterday my DPDK application crashes (haven't cleaned up DPDK and FDIR settings) and later the OS also hangs. After reboot, the OS can no longer recognize the on-board X540 NIC card. lspci and dmesg only shows a Intel NIC device 1512 ( It seems that only the device id is readable). If I enabled SR-IOV of this dead NIC card in the BIOS, BIOS would even hangs during its PCI bus enumeration. It seems to me that there are some low-level registers or MMIO regions got mess up. Best, Zongwei
